I also posted this in the Steam Forums, but it probably belongs here. Left-handed analog joystick for movement and right-handed mouse for weapons is such a good combination that I can't play any game that won't support it.

Thanks! It looks like a really great game, but I can't get out of the first room...

It sound like an engine thing. Have you tried mapping the joystick axes to keystrokes with the profiler software? It's not a nice as analog input, but I been able to use my belkin in Farcry and Doom3 quite satisfactorily.
